1. Deploy the k8s-image-availability-exporter helm chart on Kubernetes


    To deploy the k8s-image-availability-exporter Helm chart on a Kubernetes cluster using Pulumi, we'll use the kubernetes.helm.v3.Chart class from the Pulumi Kubernetes Provider. This class allows us to deploy Helm charts as part of our Pulumi stack.

    Here's a step-by-step guide, followed by the Pulumi TypeScript program to perform the deployment:

    1. Set up Pulumi: Ensure you have Pulumi installed and configured with the appropriate Kubernetes cluster context. This typically involves having kubectl configured to point to your Kubernetes cluster.

    2. Import Kubernetes Package: In the Pulumi program, we import the @pulumi/kubernetes package which provides the necessary components to interact with Kubernetes.

    3. Create a Helm Chart Resource: We instantiate an instance of kubernetes.helm.v3.Chart, which represents the k8s-image-availability-exporter Helm chart. This object takes several arguments, such as the chart name, version, and any custom values you wish to provide to the chart.

    4. Deploy the Chart: We don't need to perform any explicit action to deploy the chart. Pulumi automatically creates and manages the necessary Kubernetes resources when you run pulumi up.

    Now, let's write the Pulumi program:

    import * as kubernetes from "@pulumi/kubernetes"; // Create an instance of the k8s-image-availability-exporter helm chart const imageAvailabilityExporterChart = new kubernetes.helm.v3.Chart("image-availability-exporter", { // Chart details you usually include in helm commands chart: "k8s-image-availability-exporter", version: "2.0.0", // replace with the chart version you need to deploy fetchOpts: { // custom Helm repository URL if your chart is not in the default Helm repo repo: "https://your-helm-chart-repository/" }, // You can include custom values as per the Helm chart's configuration values: { // Your custom values go here, for example: image: { repository: "your-repo/image-availability-exporter", tag: "latest" } }, // The namespace where you want to deploy your chart namespace: "monitoring" }); // Export the base URL for accessing the service if the chart exposes it export const imageAvailabilityExporterChartUrl = imageAvailabilityExporterChart.getResourceProperty("v1/Service", "image-availability-exporter", "status").apply(status => { // Assuming your hem chart exposes a service on port 80, you can build the URL from the status info let ingress = status.loadBalancer.ingress[0]; if (ingress) { return `http://${ingress.ip}`; } return "Service not exposed"; });

    This Pulumi TypeScript program creates a new Helm chart deployment using the specified Helm chart. You should replace the chart, version, repo, and values fields with details suitable for your specific case. This program assumes that your Kubernetes context is already configured and that Pulumi can interact with your Kubernetes cluster.

    To run this Pulumi program:

    1. Save the code in a file named index.ts in a directory where you want to maintain your Pulumi stack.
    2. Open your terminal and navigate to that directory.
    3. Run pulumi stack init <stack-name> to create a new stack, where <stack-name> is a name you choose for the stack.
    4. Run pulumi up to preview and deploy the changes.

    After you run pulumi up, Pulumi will perform the deployment, and you will see the status of the deployment in your command line.

    Remember to replace the placeholders like https://your-helm-chart-repository/ with actual values that are valid for your environment. If 'k8s-image-availability-exporter' chart is available in the public Helm repository or is already added to your setup, you can omit the repo field or adjust it accordingly. The values field is a place for you to specify any configurations that the chart allows you to override. You may leave it empty if you want to use the default chart values.
